ok i havent been around and forgot what ppl told me. i have a 200 amp alt. i am going to run a kx2500.1 so how many batteries would i need. i can only fit a kinetik hc1400 under the hood. would i need more bats in the back or would i be set with just the one.
If you don't listen with your car turned off, then you don't need 2nd battery. 200A alternator is more than enough. If you want 100% safety, then install an isolator and 2nd battery. That way your starter will never be drained by the amp.
